IMPROVEMENT IN APPARATUS FR PRESERVING- AND FREEZING- FISH, MEATS, &c.

The Schedule referred to in these Letters Patent and making parttof the same.

To all whom it may concern Be it known that I, PHLLIP N UNAS, of Sandusky, in the county of Erie, and in the State of Ohio, have invented certain new and useful Improvements in Apparatus for Preserving and Freezing Fish, Meats, 86o.; and do hereby declare that the following is a full, clear,

and exact description thereof, reference being had toA the accompanying (h'awings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction and general arrangement of a double house, with an apparatus for producing cold, thereby preserving and freezing iish, meats, or anything else placed in the saine.

In order to enable others skilled in the art to make and use my invention, I will now proceed to,desc1ibe its construction and operation, referring to the annexed drawings, which form a part of this speciiication, and in which Figure 1 is a longitudinal section, and

Figure 2 is a side view of the apparatus, in one of the chambers of the house..

Figure 3 is a bottom view ot' the same, of reduced dimensions.

Arepresents the outside casing of my freezing-house, constructed of two walls, a a, all around which walls are, at a suitable distance from each other, and the space b between them, filled with sawdust, or other non-conducting material.

Inside of the outer casingA is placed an inner casing, B, which is constructed, in like manner, of ytwo walls c c, anda space, d, filled with `non-conducting material.

The inner casing B is so placed as to leave a space, c, between it and the outer' casing, which is left vacant, and servesA for Ventilating-purposes, openings being made, vfor that'purpose, at lconvenient places, through both casings. l

The inner casing B is divided into two or more apartments, as shown in g. 1; the partitions between the different apartments to be made in the same manner as the walls, that is, double-walls, the space between them filled with some non-conducting material.

Doors, at suitable places, lead into the inner casing,

and to all the different apartments.

From the centre of the roof of each apartment is suspended a circular vessel, C, from which pipes D D lead downward, the lower ends oil 'these pipes being h of the inner casing', if so desired.

The fish, meat, or other article to be preserved, is

placed either on the oor ofthe inner casing B, or

suspended from rafters in the same, and the Vessels D and F F iilled with a compound, consisting of pulverized ice, salt, and crystallized muriate of lime, which produces intense cold, 'freezing the varticles put in the house iu a short time, thus preserving them, so that they may be kept for any period desired.

Any liquid that may escape from the above-mentioned compound is carried on, by Vmeans of hose or pipes, attached to the pipes E E and the vessels F F.

I am aware that preserving-houses, formeat, iish, 85e., with receptacles suspended fromthe inner side of the same, filled withice and freezing-mixtures, are not new.

In a meat and fish-preserving house, having compartments B B, withl walls, as herein described, thecombination of the vessel G, pipes D and E, and vessels F F F F, all suspended in thc house, so as to allow a space below them, -for the articles, substantially as herein shown and described.-

In testimony that I claim the foregoing, I have hereunto set my hand, this 11th day of August,'1868.
